Motorcycle Luggage Decoupling Device for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage systems for single-track motor vehicles, such as motorcycles and scooters, are complex, expensive, and cannot be retrofitted, often restricting passenger movement and failing to effectively reduce pendulum movements caused by luggage during driving.
Innovation Solution
A simplified luggage system featuring a decoupling device that partially decouples luggage from the receptacle using an elastic inner wall, foam, or a hanging device to absorb and phase-shift travel-related forces, allowing relative movement and reducing the impact on the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If complex constructions are used in the luggage holder to prevent swaying, then the stability of the motor vehicle is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The luggage holder is divided into an outer rigid shell and an inner decoupled receptacle that can move independently. This segmentation allows the outer shell to maintain vehicle stability while the inner receptacle absorbs pendulum movements, reducing the need for complex stabilization mechanisms.
Solution Approach 2:
A decoupling device acts as an intermediary between the luggage and the motor vehicle frame. This intermediary component absorbs and isolates the forces generated by luggage pendulum movements, preventing them from being transmitted to the vehicle frame and eliminating the need for complex anti-sway constructions.
2Strength
If rigidly fixed luggage systems are used, then the structural strength is improved, but the ability to reduce pendulum movements is worsened
Solution Approach 1:
The luggage receptacle is designed with dynamic characteristics, allowing it to move and deform in response to pendulum forces. The decoupling device enables controlled movement and energy absorption, transforming the rigid system into a dynamic one that can dissipate harmful forces rather than resisting them statically.
Solution Approach 2:
The decoupling device is pre-configured with energy-absorbing characteristics (such as elastic elements or friction mechanisms) that are activated when pendulum movements occur. This beforehand cushioning allows the system to absorb and dampen forces before they can significantly affect vehicle stability.
3Manufacturing precision
If integrated luggage systems are used, then the manufacturing precision can be maintained, but the ease of manufacture and retrofitting capability are worsened
Solution Approach 1:
The luggage system is segmented into modular components: an outer holder that attaches to the vehicle and an inner receptacle that attaches to the outer holder. This segmentation enables independent manufacturing and assembly, allowing the inner receptacle with its decoupling mechanism to be produced separately and installed without complex integration, facilitating both manufacturing and retrofitting.
Solution Approach 2:
The outer luggage holder is designed with universal mounting features that can accommodate different vehicle types and luggage configurations. The decoupling mechanism is integrated in a way that provides multiple functions (mounting, decoupling, and structural support) through a single component design, simplifying manufacturing and enabling retrofitting across different applications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The decoupling device effectively reduces pendulum movements and centrifugal forces, enhancing ride stability and mobility while being cost-effective and retrofittable.
Implementation Method 1
the inner wall of the baggage receptacle (2) is formed as an elastic, deformable wall (4) with cavities, in a sandwich construction or in foam
Implementation Method 2
The inner wall designed in this way enables a relative movement of the item of luggage in relation to the item of luggage receptacle, so that there is a phase-shifted introduction of force via the item of baggage receptacle to the motor vehicle
Implementation Method 3
the hanging device is implemented as an elastic fabric net or elastic rubber tub. The embodiment variant corresponds to a kind of 'hammock' for the item of luggage inside the item of luggage receiving container
Implementation Method 4
the hanging device is implemented as an elastic fabric net or elastic rubber tub
Implementation Method 5
so that relative movements can be implemented. The mobility is limited by appropriate mounts or a combination with a lining of the inner wall of the luggage storage container
